VII. UPS REMOTE MONITORING AND CONTROL
Following external connections are available for DS300SHA Series UPSs.
•
Communication by serial port connection.
•
Dry contact (interface board) connections.
•
Remote monitoring panel.
Using one of above communication options is satisfactory for remote monitoring and control in most of the
systems. But in some systems may use 2 or 3 of above options at the same time. In this case accessories
group produced by Tescom may help to make appropriate solutions.
7.1 Using Serial Port
One serial communication port is available on DS300SHA Series UPS cabinet (com1 and com2). This port
may be used for user communication. But in service status duty of this com port is changed and set as
service port in Options Menu.
All data of UPS can be accessed by this communication way. All the voltage and current values measured
by UPS, alarms, warning and status messages can be monitored.
Because the communication system is designed in an interactive manner, UPS may get commands from
monitoring and control units. These commands are listed below:
•
Switch to BYPASS
•
Switch to INVERTER
•
SOUND on/off
•
Adjust UPS time and date
•
Quick BATTERY TEST
•
BATTERY TEST until battery low alarm
•
CANCEL battery test
•
Turn off UPS output voltage immediately (SHUTDOWN)
•
Turn off UPS output voltage after delay (WAITING SHUTDOWN)
•
Turn off UPS output voltage (SHUTDOWN) and turn on UPS output voltage (WAITING RESTART)
•
CANCEL SHUTDOWN
•
RENAME UPS
These commands are evaluated only if REMOTE CNTRL: ON option is selected in
OPT İ ONS/COMMUNICATION OPTIONS menu and if user password is sent from this (com2) port.
Otherwise UPS doesn’t perform these commands and only information can be obtained from the ports.
Special softwares are required in order to use the serial communication ports. Some of the commands
above have special functions and they can only be activated and used by operating TMON program groups
on a PC that is serially connected to UPS.
TMON program group includes softwares developed by TESCOM.
Additionally, remote monitoring and control is provided in every kind of operating systems, by using
worldwide known and continuously devoloping software programs. These softwares can be supplied from
TESCOM.
7.2 Serial Communication Port Connection Cable
The maximum length for RS232 communication cable should be 25 meters. For remote panel and UPS
connection the same pin configuration is valid. Connection terminals of RS232 cable is shown below for
com1 and com2 ports:
